摘要： A composite membrane comprises a substrate made from a polymer selected from copolymers and homopolymers of ethylenically unsaturated nitriles, which substrate has preferably first been treated with a pore protector in absence of curing agents and catalysts therefor, prior to applying as the final coating a silicone layer, which is crosslinked. The pore protector, which may be, for example, a hydroxy-terminated polysiloxane, particularly a silanol-terminated polysiloxane, serves the dual purpose of preventing the pores from collapsing, when the support is dried during the curing of the silicone layer, and of preventing passage of the coating material deeply into the pores and thus also preventing an undue reduction of the flux of the finished coated membrane. Such composite membranes include solvent stable membranes which swell to an extent of no more than about 10% when immersed in various organic solvents, and their mixtures with each other and/or water.

摘要： A composite membrane which is substantially insoluble (and preferably swells no more than 10%) in acetonitrile, ethanol, hexane, toluene, N-methylpyrrolidone, dimethylsulfoxide, dimethylformamide, dimethylacetamide, and their mixtures with each other and/or with water, comprises a substrate made from copolymers or homopolymers of ethylenically unsaturated nitriles, the substrate having been subjected to the steps of: (1) insolubilizing the polymer by crosslinking; (2) coating with a silicone layer; and (3) crosslinking the silicone layer. Prior to step (2), the substrate is preferably treated with a pore protector in absence of curing agents and catalysts. The pore protector is e.g. a hydroxy-terminated polysiloxane, particularly a silanol-terminated polysiloxane; it prevents the pores from collapsing, when the support is dried during step (3), and prevents passage of the coating material deeply into the pores, thus also preventing an undue reduction of the flux of the finished membrane.

摘要： The present invention relates to semipermeable mosaic polymer membranes of asymmetric structure and with a macroscopic distribution of the mosaic-forming anionic and cationic charges (sites). The membranes can be prepared by casting a polymer solution of an optionally charged matrix-forming polymer and at least one precursor polymer, incompatible with the matrix-forming polymer, in a selected solvent, into a film, forming a skin on one side of the film, precipitating the skinned film to form the asymmetric membrane and charging it by chemical reactions to introduce or complete their mosaic structure. These membranes have good permeability for electrolytes, such as salts of mono- or polyvalent inorganic acids, while retaining low molecular weight organic solutes.

摘要： A process and apparatus for the continuous separation of electrically charged macromolecular compounds, such as proteins, by forced-flow membrane electrophoresis is provided.Said process is conducted in an electrophoretic cell comprising a membrane compartment, divided by a micro- or ultrafiltration membrane into a feed and permeate cell, and electrode compartments being partitioned from the membrane compartment with ion-exchange membranes, which are impermeable to the macromolecular compounds, and have virtually no permeability to salts.The electrophoretic process comprises the steps of recycling a mixed solution of the charged compounds which are dissolved in a separation buffer through the feed cell, subjecting of the solution to a pressure-driven membrane separation, applying an electric field across the membranes and the solution to cause electrophoretic migration of the charged compound and to separate them, and withdrawing the charged compounds thus separated.The process achieves separation of charged compounds having differences of their isoelectric points in a range of as low as 0.1 to 0.2. The process is very useful to remove charged contaminants from the desired compounds.
